Finally able to block the psiphon with the help of tac.

The procedure is :

-install the latest hotfix in both gateway and management (may or may not be required)

- Enable https inspection and generate the self sign certificate.

- generate self-signed certificate and install it on all PC of the network (Would be easy if Active Directory is in use)

- Make a Policy for https inspection with "https" and "http_and_https_proxy" with ACtion=Inspection

- Add url and application policy to block the category "support file sharing".

Note: the psiphon is block for only devices in which we install the self-sign certificate. 

Thanks,

successfully block PSIPHON3 application we need to have HTTPS Inspection enabled on the gateway and the entire subnet in question should be subjected to HTTPS Inspection.

Enabling HTTPS inspection in a college environment is hard, because many are Mobile phone users. After installing the ssl certificate a warning message is showing- your device is monitoring a third party.  At the time of device implementation, we successfully blocked all the tunnelling application without enabling HTTPS inspections. But on the recent Application Blade database update, these applications started getting connected.

If you want to block this application, you will must to block all VPN which are not yours. You may read about Psiphon for PC here or just follow the steps below to unblock the app:--

1. Enable DPI-SSL Client Inspection by going to DPI-SSL | Client SSL and selecting Enable SSL Client Inspection. Ensure that IPS, GAV, Spyware, and Application Firewall are selected.

2. Enable all Psiphon application signatures by going to Firewall | App Control Advanced. Select the category PROXY-ACCESS and application Psiphon. Configure the application to be blocked and logged.

3. Also block Encrypted Key Exchange TCP Random Traffic (SID 5).

4. Enable blocking of SSH app signature (SID 10097) "SSH -- Client Request Outbound", (or make access rule to block outbound TCP/22 SSH Service from LAN->WAN).
